Rusty caliper "bolts" - Warranty item?

[Mousem40]

It doesn't look like it's available as a spare part from Porsche

See p.96+ in the Porsche Parts Catalogue (PET) Cayman 2009 onwards version below

I would not be happy for a rusty bolt like that to be on show on my caliper.

I would either buy new bolts (from Porsche or an engineering company)

Or, put vinegar on them and agitate with a wire brush. (Works wonders, I've done this many times before)

On my 2011 Cayman, these bolts have plastic covers so I assume that they won't be rusty underneath. But I won't be pulling these covers off to check.

Thanks for the link, But I can't see a p.96? Are you saying it shows the 987 has captive nuts and this is why they're irreplaceable, as has been suggested?

I second this... I want rust free bolts on my car, even if it wasn't a Porsche.
The rusty bolt is simple - the wheel cleaner used was left on too long or not rinsed correctly. It happens all the time.
A good dealership will have this knowledge.
An amazing dealership will offer to replace them next service FoC.
Not a warranty issue for sure, but the knowledge would have reassured the customer.

Not doing it is a lost opportunity to win the loyalty of a customer. I travel 3 hours in traffic to get my audi serviced at a specific dealership because they are fantastic, and do these details.

Don't get why all the haters be hating.

Thanks for the support and info.

The details matter to some, especially if your at the end of a long list of issues with your car. cut the guy some slack.

it does sound like you have couple of options, replace bolt if it screws out, or clean and paint.

Thanks for the support and info.

If it was my car, as suggested already, I'd get some rust remover and re touch with a little silver paint. It will cost far less than buying bolts and paying someone to fit them.

Having spent this weekend replacing the exhaust back box and N/S cat on my 2001 Boxster, I'm struggling to have too much sympathy for the OP.

The state of all the bolts holding the exhaust together was incredible, many were not longer there, and those that were were mainly rusty little nubs either side of the fittings. I don't know what spec metal Porsche selected for it's production lines, but it's certainly not corrosion resistant!

Erm... 15 years old vs. 2 years old.

Good point. I mean you would expect that older Porsches were built better eh?

It is quite possible that you have ALL of the pedantic cards.

But yes, I agree. Its the materials that are better. The air cooled cars are hopelessly over engineered. 911SC engine has the same architecture and internals as the turbo. Why? Dunno. But I love Porsche for it. Of course, this is not possible anymore.

In terms of build, it was during the 993 period that Porsche really got to grips with quality. They consulted with Toyota (or was it Honda?) and began their journey to where they are now.

Its not really in their interest (financial) for the orginal car to last forever.

Well, doh, I'm aware of that, it was a comment on the standard of materials Porsche use for some of their fittings. The Boxster I bought new in 2001 had corroding wheel nuts within the first year. I couldn't see the point in asking for replacements as they'd have just started corroding the same. However, I will accept that I should have as it's only when the customer keeps coming back for free replacements that the manufacturer will bother spec'ing better OEM.

Not surprisingly when I bought this Boxster 2 year back, at 13 years old, one of the first jobs was fitting a new set of after market wheels nuts, as not just the nuts were corroded but the alloy collars were disintegrating too. Now that's NOT good as they hold the wheels in place!

That's the first time I've seen a 981 caliper. It now looks like you have to remove the caliper to change the pads! What a PIA that will be if you change pads regularly for track days. A real step backwards from what has always been a great design of caliper that used to mean change pads was a doddle.

[DJMC]

Note that all the black finish has disappeared from my callipers, apart from the face of them. This doesn't bother me so much, but is no doubt down to (or the OPC would say it is) acid wheel cleaner.

I'm just going to ask the previous owner, out of interest, if he ever used it...

I haven't.

I'll speak to Brembo or a specialist about the pad slider bolts, just to see if the are captive in manufacture OR available at reasonable cost if easily replaceable.

Let us know how you get on. I have exactly the same problem - I have had my car from new and I never use acidic wheel cleaner.

[nsm3]

I'd be tempted to get these painted gloss black. I'm on my 3rd set of gloss reds on Porsches and apart from the odd stonechip, the finish stands up really well, alloy wheel cleaner, Muck Off, whatever is used on them?

[DJMC]

Spoke to prior owner. He never used wheel cleaner, just jet washed the car a few times.

It was a Porsche GB car for the first 6 months, so it may have been Reading that used wheel cleaner. That I'll never know...

[V800MJH]

Unless we are classing acid as wheel cleaner then I can't see it being the prime cause of this.

I use and have used wheel cleaners on all my car for years. Iron-X, Tardis etc.

Never have I had a caliper bolt corrode like this.
